Wilbur D. May Arboretum & Botanical Garden
Located within Rancho San Rafael Regional Park, the Wilbur D. May Arboretum & Botanical Garden is a unique showplace for plants and wildlife living in the transition zone between the Sierra Nevada and the Great Basin Desert. Established in 1983, the Arboretum is home to over 4,000 native and non-native plant species, and covers nearly 23 acres. Funded by the Wilbur May Foundation, the Arboretum is a tribute to philanthropist Wilbur D. May. Owned and operated by Washoe County, the Arboretum receives funding from the May Foundation, the May Arboretum Society and private donors.
These unique, high elevation gardens showcase diverse native and non-native plant communities and offer seasonal displays of spring flowering perennials, summer annuals, majestic fall colors and breathtaking vistas of the Truckee Meadows and the Sierra Nevada Mountain range. The Arboretum is a place for all ages to learn, explore and engage the senses while discovering what the plant kingdom has to offer.

Gravel paths may be wheelchair accessible when dry, but can become quite muddy if the weather has been wet.
